As the title says I know this is getting asked ALOT around here, but I thought one more thread couldnt hurt.
I have a feeling that my PSU is providing me with enough power. I cant explain why, I just think thats the root of all the issues I have after getting a new GFX card. This is the unit. Took me a while to find the (almost, mine is v2.0) correct version and while looking around the comments werent nice.
Using 5830 gfx, Q6600 @ 3.2, 4gb ram, 3 HDD's and 1 DVD-R.
I tried the PSUcalculator thing but that say much about the quality of my current gear.
The better PSUs, will be rated as 80 plus gold/silver/bronze.
Yes, agree! That is the proper terminology to describe a PSU. And if it is not 80+, let them just state the max efficiency, not "up to ---". Reminds me of "up to 75% discount" whereby, a 2% discount would still be within the advertised statement.
One way to look at it is: If your PSU wasn't strong enough, then it shouldn't even POST... As another poster has stated, your V12+ rails are a bit weak ontop of that your OCing your card, Plus ATI's drivers aren't exactly know for stability....
I would say set your card to stock settings, and research the drivers for a "known" stable driver.... Give that a shot, and if it doesn't crash... Then your issue was the driver or the OC... OC it a little and "wait and see", if it crashes, there is your problem the OC.
The PSU looks like it is an obsolete design (note the really heavy 5 volt rail) dressed up with passive PFC. And 34 amps, even if that is the maximum 12 volt current, is light for a 550 watt PSU. A 450 watt Corsair produces 33 amps. A 550 watt Corsair produces 41 amps.

Not exactly true. While the system is POST'ing, it's under a minimal load and the graphics card is loafing along under a 2D load. Even in an older video card, going to a 3D gaming load will double the power it consumes.
If your system is resetting/rebooting, you probably have one or more of the following problems:
1. Unstable overclock. I don't like overclocking graphics cards. The temps run too high anyway.
2. Unstable drivers.
3. Inadequate 12 volt power.
